'Ready' in the Bible

This is the one of whom it is written [by the prophet Malachi],‘Behold, I send My messenger ahead of You,Who will prepare Your way before You.’

He answered and said, “Elijah is coming and will restore all things;

Therefore, you [who follow Me] must also be ready; because the Son of Man is coming at an hour when you do not expect Him.

[Accordingly] the disciples did as Jesus had directed them, and they prepared the Passover.
